i planted these palms (3) in my yard back in november- the dry season (central coast FL). they did fine, are in a spot where water drains to in rain; they are also planted in a neighborhood where once was a bog so nutrients etc and sandy soil type are perfect. i do realize that all plants and trees from many nurseries are pumped full of fertilizer to the point they are used to getting nutrient availablity very easily- without working for it - so there can be an adjustment phase of 'not so good lookin' and then weeks later- they are fine. so we move thru dry season with less water, then jump rainier season- lots more water suddenly; and then the dark kinda necrotic rim on the fan leaves shows up. i use a palm fertilizer- spikes- and the leaves look better, then a brush fire came thru and scorched many of those leaves on the edges (burned up the wood behind us), this was april now. it is 1st of aug and they have come back.... BUT, the leaves in my opinion, are not branching as high and wide out as they should or were. its almost as if the newest leaves, very healthy looking and all, are keeping themselves very much close to the meristem. i guess for a palm, the 'frond's or petiole parts are not stretching their longest. is this a Boron deficiency or just a growth phase and i should leave it all alone and allow them to adjust some more over time. they are about 3 yr old palms that were in container before purchased so they are only about 6-7 feet tall at this point.
